       1. A compound imparting durable antistatic properties to polyamide materials and of the general formula: ##STR6## wherein R is a C 1-9  alkyl group or hydrogen, Z is a difunctional chain modifier group, R' is a C 1-4  alkyl group or hydrogen and x and y are between about 10 and about 50. 
     
     
       2. The compound of claim 1 wherein R is C 1-5  or hydrogen. 
     
     
       3. A compound for imparting durable antistatic properties to polyamide materials and of the general formula ##STR7## where R is a C 1-5  alkyl group or hydrogen, Z is a difunctional chain modifier group, R 1  is a C 1-4  alkyl group or hydrogen and x and y are each between about 20 and about 40. 
     
     
       4. The compound of claim 3 wherein R is a hydrogen radical. 
     
     
       5. The compound of claim 4 wherein Z is a C 2-18  dibasic organic acid or derivative thereof. 
     
     
       6. The compound of claim 4 wherein Z is azelaic acid or a derivative thereof. 
     
     
       7. A static resistant polymeric composition comprising: a polyamide; and   an antistatic compound of the general formula: ##STR8##  wherein R is a C 1-9  alkyl group or hydrogen, Z is a difunctional chain modifier group, R is a C 1-4  alkyl group or hydrogen and x and y are between about 10 and about 50.   
     
     
       8. The composition of claim 7 wherein R is C 1-5  or hydrogen. 
     
     
       9. The composition of claim 8 wherein x and y are each between about 20 and about 40. 
     
     
       10. The composition of claim 9 wherein R is a hydrogen radical. 
     
     
       11. The composition of claim 10 wherein Z is a C 2-18  dibasic organic acid or derivative thereof. 
     
     
       12. The composition of claim 11 wherein Z is azelaic acid or a derivative thereof. 
     
     
       13. The composition of claim 7 wherein said polyamide is nylon 6, nylon 6/T, nylon 6,6, nylon 12, copolymers and mixtures thereof. 
     
     
       14. The composition of claim 13 wherein said antistatic compound is about 0.5% to about 12% by weight of said polymeric material. 
     
     
       15. The composition of claim 14 wherein said antistatic compound is about 2% to about 6% by weight of said material. 
     
     
       16. A process for preparing an antistatic polyamide fiber comprising: a) mixing with a polyamide a compound of the general formula: ##STR9##  wherein R is a C 1-9  alkyl group or hydrogen, Z is a difunctional chain modifier group, R' is a C 1-4  alkyl group or hydrogen and x and y are between about 10 and about 50, the composition being added in sufficient quantity to impart antistatic properties to the resulting mixture; and   b) extruding the resulting mixture.
